To all 'whom z't may concern Be it imown that I, MILTON C. Lenoir, a

citizen of the United States, residing at Chi- `cago, in the county of Cook and State of my invention consists in the novel features.

and in the novell combination and arrangement of parts vhereinafter fully described,I

illustrated in the accompanying drawings forming a part of this specification, and particularly pointed out in the claims hereunto appended. y

In the accompanying drawings, Figure 1 is a horizontal central section; Fig. 2 is a cross section on line 2 2 ofiFig. l; Fig. 3 is a view in perspective with parts broken away; Fig. 4 is a perspective view of the carrier; Fig. 5 is a vert-ical cross sectional view of the driving and driven members in position for rotation in the direction indicated by the arrows.

The embodiment herein disclosed is applied to the rear divided axle of an automobile.

Like parts are identified by the same reference numerals views.

Referring to the drawings by reference numerals, 1 denotes the opposing ends of a divided axle having squaredinner ends 2, on which are the respective hubs 8, each having a s uared axial opening 4 therethrough. Integra with each hub, or attached theretoj on each axle is the web portion 5 and the inwardly extending ange 6 with smooth inner face 7 The respective driving parts are desig-` ythroughout the severall Y A-sitely disposed planes onwhich the rollers 15 and 16 travel into and out o'f engagement with the adjacent surfaces of the respective driven flanges 6, 6. -The star shaped driving members 11 and 12 have concentric slots 17 and 18, respectively, for purposes hereinafter explained. 19, 19, indicate hub portions of a'rotatabl housing 19, 19? whichis fixed to the bevel gear wheel by bolt 19".

For the purpose of carrying and positively driving the rollers 15 and 16, I have provided two sets of carriers 20,21, 22 and 23, which are coupled to a sleeve 24 by means of keys'25 and move simultaneously.

The reference numerals (see Fig. 4) 26 and 27 designate preferably integral sleeves carried by parts 20 and 23, with bolts 28 and .29, respectively, which have screw threaded engagement with the respective `segmentsof `the carrier rings 21 and 22.

There is formed an annular series of journal recesses 30,in the opposing surfaces of the pairs of carrierl rings, each Vrecess has walls 31 and 32 to limit the movement of the rollers journaled therein. The bearings 33, resting upon the hubs 19, 19 of the ro.-` tatable housing, support the non-rotatable housing 34. The .bearing 35 supports the shaft 36 with its bevel pinion 37 in mesh with the bevel gear 9.

The'drivingV parts 11 and 12 are at liberty -to engage with and release from the drums or flanges 6, 6, through the rollers 15 and 16 .on movement of the carrier from normal position shown in Fig. 2 to the position shown in Fig. 5 when moving in the direction of the arrow. The length of the concentric slots in the parts 11 and 12 is in'- tended to be suiicient to permit reversing the positions of the walls 31, 32 with respect tothe rollers.

In operation, when the bevel gear wheel 9 is rotated in the direction indicated by the arrows in Fig. 5 the part 11 will rotate independently until the sleeve 26 contacts with the end of the-slot 17 when the parts 5, or driving position. Suppose the vehicle wheel operated by the parts last mentioned lis describing a longer radius curve and the speed of part 6 is greater than that of the part 11, then the parts are in the positions shown in Fig. 2, and the Wheel is at liberty will be in the positions shown in said Fig.l

'to rotate reelv until a forward direction is 1,10

again talren When povver transmission engagement is vestablished as before.

lt will be understood that changes, variations and modilieations in the details of the invention Within the scope of the claims shafts, a driven member fixed to one end ot each shaft, rollers supported by each carrier, and a driving member formed to Wedge the rollers of each carrier in o grip engagement with the respective driven members.

2. In differential mechanism, a plurality of carriers composed of pairs of rings and bound together and capable of a substantially simultaneous ,lrrotative movement, each pair of rings having an annular series of journal recesses in the opposing surfaces thereof to limit the movement of the rollers therein.,

i Losanna 3. 'ln dil'erential mechanism, the combination of a non-rotatable housing and a rotat-able housing and a driving member`hav ing concentric slots carried therein, a driven member, a plurality of rollers, carriers hav.`

'ing journal recesses to limit travel 'of said rollers with respect vto the carriers. j

j Ll; ln diderential mechanism,` the combination of a driving membervhaving a plurality of concentric slots therethrough and oppositely positioned inclined planes, rollers operable upon said inclined planes, and carriers having journal recessesto permit travel of the rollers.

5. In dierential mechanism, the combination of a driving member, driven members, a plurality of carriers bound together and capable of a simultaneous rotative movement, rollers supported by the respective carriers, the carriers and the driving member havingl relative movement.
